MJRemi Posted November 22, 2010 Share Posted November 22, 2010 Since I just bought this project MJ knowing the tranny is going south, I don't want to put money into a BA10. I will put a reman ax5 or ax15 in it's place but I don't know the pros & cons of either one. Is the ax15 better and are there issues with fitting it into place when the BA10 comes out. This truck is going to be a very good quality restoration project so I don't mind reasonable differences in cost. 1988 MJ 4.0 2wd 5spd Any input is appreciated. Thanks!

JeepcoMJ Posted November 22, 2010 Share Posted November 22, 2010 the only bolt in substitute is an ax15. there's not even a bellhousing to make the ax5 work with a 4.0. if you swap in an ax15 from an '89 to '92, it is a bolt-in setup, requiring only that you swap to an ax15 crossmember...you will need a 23 spline transfercase to go to ax15.

MJRemi Posted November 22, 2010 Author Share Posted November 22, 2010 I'll look around for those years. I want this to be as simple of a swap as possible. The cross member info is good to know. Pardon my ignorance on the next one. Do I need a transfer case on a 2wd? Quote Link to comment Share on other sites More sharing options...
JeepcoMJ Posted November 22, 2010 Share Posted November 22, 2010 no, you don't. but good luck finding a 2wd ax15.. Quote Link to comment Share on other sites More sharing options...
